ex stored proc and COM objects

Am I right in stating that I cannot create COM objects using ATL inside of
an extended stored procedure? I have need to use an ADODB.Connection object
to communicate with our LDAP. Originally we were just going to use
sp_OACreate in a "regular" stored proc, but since we need to permit
non-admin types to execute the stored proc, that is out of the question. I
figured an ex proc is the only way to go now, but have the COM issue with
which to deal.
Any hints or suggestions?

Not to my knowledge. Why do think there will be
a problem specifically with ATL? Apartment threading issues?
